Mariah Carey would “rather be on stage with a pig” than duet with Jennifer Lopez. The ‘Hero’ singer slammed rumours she was planning to collaborate with pregnant J Lo, saying it would “never happen”. When asked about a possible duet, she fumed to US TV show ‘Inside Hollywood’: “I’d rather be on stage with a pig! A duet with Jennifer Lopez and me just isn’t going to happen.”

This isn’t the first time the diva singers have come to blows. They first crossed swords in 2001 when Jennifer sampled two songs from the soundtrack to Mariah’s movie ‘Glitter’ in two versions of her own hit track ‘I’m Real’ for her album ‘J.Lo’ An insider on the set of ‘Glitter’ said at the time: “Mariah was so paranoid about the music getting out that we had another singer sing the temporary versions before the film was released. “When Jennifer Lopez’s album ‘J Lo’ came out, and had the exact same song on it, we knew she had a right to be paranoid. We couldn’t believe her audacity.”

Shortly after the scandal, Mariah was interviewed for German television and questioned about fellow divas. When asked about former ‘Destiny’s Child’ singer Beyoncé Knowles, Mariah complimented her beauty and talent. But when she was questioned about Jennifer, Mariah looked incredibly uncomfortable and said: “I don’t know her.” The feud was recently reignited when Mariah was told Jennifer has eight hours of sleep a night. She cattily laughed: “If I had the luxury of not actually having to sing my songs, I’d do that too.”
